Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Under the present test conditions no toxic effects caused by the test item were observed at a nominal concentration of 100 mg Imwitor 370/L exposure medium in a limit test. None of the animals died.
Key value for chemical safety assessment
Additional information
In a 96-h acute toxicity study according to OECD 203 and GLP, zebrafish (Danio rerio) were exposed to the test substance (CAS 91744-38-6, Glycerides, C16-18 mono-, di- and tri-, hydrogenated, citrates, potassium salts) at concentrations of 0 and 100 mg/L nominal (limit test) under semi-static conditions. The 96-h LL50 based on mortality was > 100 mg/L. No sublethal effects were observed. Based on the results of this study, the test substance would be classified as non-toxic to Danio rerio.
Although the test substance has a low water solubility and the actual test concentration was not verified, the study is classified as acceptable. In WAF procedure, suspensions of the 300 mg test substance were prepared in 3L drinking water and shaken at room temperature for 24 h. After 24 h the shaking was stopped and the solutions were filtered through paper filters directly into the test vessels used for the test. Therefore it can be concluded that the test substance is not toxic at a loading of 100 mg/L (NOELR = 100 mg/L).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
